This application is in part a continuation of my application Ser. No. 304,125, filed September 5, 1928.

The machine in its preferred embodiment comprises a supporting frame .which may be formed in separate parts, for example, a lower part 2 and an upper part 4. Pivoted to the lower part of the frame is a bracket 6 vertically adjustable through the medium of a screw 8 threaded therein and engaging a fixed portion of the frame and carrying a motor 10 provided with a pulley 12' about which may be trained belts for driving various portions of the mechanism. The upper portion 4 of the frame has pivoted thereto on a fixed rod 14 a saw table 16 the horizontal position of which is determined by engagement with a stop screw 18, the table being adjustable above this position through an adjusting screw 20 which is threaded in the frame and engages the table, its adjusted position being held by reason of the provision of a lock nut 22. In order to prevent any looseness of theitable, a. rod 24 is arranged to be adjustably fixed in the frame and engage the bottom of the table in its various positions.

- Projecting upwardly through a slot in the table 16, or preferably through a slot in an insert in the table, is a circular saw 26 which may be either a combined cross-cut and rip saw, or either of these types. The saw is removably carried on. the end of a mandrel 28 j ournalled in the frame and carrying a pulley 3O vertically above the pulley 12 and adapted to be connected thereto through the medium of a belt 32. A fence 33 having opposed finished surfaces so that it may be used either on the right-hand or left-hand side of saw 26 slides in a transverse slot 36 formed in the forward edge of the table, being held in adjusted positions therein by means of a clamp- 44. The lathe bed 42 is lengthwise adjustable in the frame, being held in adjusted position by nuts 43 threaded upon bolts projecting from the frame'and passing through slots 1n the bed. A tail'stock 46 is adjustable on the lathe bed in the usual manner. Suitable supporting members for holding work to be sanded or to be bored may be secured to the lathe bed. The lengthwise adjustment of the bed relatively to the frame provides ready means for changing the floor space occupied by the machine, the lathe bed being moved inward to conserve space when its entire length is not needed.

On the right-hand side of the saw table 16 is a jointer 48 carried by a spindle extending in parallelism, with the mandrel 28 and carrying a pulley 52 lying in the same vertical plane as the pulley 30 and at substantially the same distance from the pulley 12 so that the belt 32 may be used alternately to drive either the mandrel 28 or the jointer. Tables at the front and rear of the jointer are vertically adjustable in the usual manner for adjusting the depth of cutting. Since it is undesirable to have both the jointer and saw operating at the same time, the alternate use of the'belt 32 is unobjectionable and in fact is very convenient, since the change from one to the other may be very readily effected, this change being facilitated by the manual raising of the table-16t0 an extreme upper po sition.

In order to properly guide work presented to the jointer,there is provided a fence arrangement, illustrated in plan in Fig. 7 and in sectional detail in Fig. 8. y sists of a guiding plate 54 adjustably carried sothat it may assume either a vertlcal position perpendicular tothe jointer axis or a sloping position as indicated in dotted lines in Fig. 8. To effect this adjustment. one of the tables 50 is provided with bracket extensions 56 on which is supported a supporting member 58 slotted as indicated in Fig. 7 and held in fixed'position by manually adjustable screws 60 threaded into the brackets 56. Pivoted to upstanding members 62 carried by the supporting member 58 are links 64 which are also pivoted to the guide plate 54. A link 66 is also pivoted to the guide plate and slotted as indicated at. 68 to permit the pas sage of a screw 70 which passes through the slot and is threaded into an upstanding post carried by the member 58 whereby the link clamped in adjusted position.

66 may be thereby determining the angular position of the guiding plate 54. The vertical position of plate 54 is determined by an adjustable stop screw 72 against which it abuts when invertical position.

Journalled in the table 16 is an upright spindle 74 arranged to carry at its upper end This fence coni i on a vertical axis. At its lower end the spindle 74 carries a conical follower member 78 provided with suitable friction facin material. Below the spindle 74 is a clutc member provided'with opposed conical surfaces 80 extending on op osite sides of the follower 78, this member being splined to' a shaft 82 and urged towards the right, as illustrated in Fig. 3, by a spring 84 against a cam 86 pivoted to the frame and provided with three cam faces 88, 90 and 92 'at different distances from its pivot. By the adjustment of the cam 86 manually to bring the various faces into engagement with the clutch member either of the conical faces 80 may be engaged with the follower or, alternatively, a -central position may be assumed in which the follower member is not engaged. As a result, if shaft 82 is driven in one direction, either a clockwise or counterclockwise rotation may be imparted to the spindle 74 by suitable adjustment of the cam.

It is found desirable to form the faces 80 1 of aluminum, since proper frictional engagement is thereb provided without danger of heating at t e high speeds, of operation.

Motion is imparted to the shaft 82 through a pulley 94 carried thereby over which is trained a cross belt 96 adapted tobe driven from the pulley 12 of'the motor. When the belt 96 is used the belt 32niay be removed. However, hereagain no inconvenience is caused, since the shaper is not used at the same time as the saw or jointer. The pulleys 94 and 12 are, of course, in the same vertical plane together with the pulleys 30 and 52.

In order to properly present work to the shaper, particular y when tenoning is being done, there is provided a iding element consisting of a base 98 slida Is in a slot 100 formed in the table 16. Pivoted to the base 98 about the vertical axis is a supporting .earrier 102, including a base and a. vertical fence designed to enga 0 material to be operated upon to proper y hold the same in alignment, a screw 104 being rovided to clam the work in position. e adjusted angu ar relationshi between the member 102 and the base 98 1s maintained by the engagement within a slot 108 formed 1n an extension of member 102 of a stud carried by the base 98 on which is threaded a wing nut 106 designed to clamp the two parts together. I

At its inner free end the shaft 82 carries a clutch element 110, this arrangement bein shown in detail in Figs. 5 and 6. The clutc element 110 is provided with a noncircular opening 112 adapted to engage a correspond ing projection 114 on a shaft 116 which drives the lowerpulley 118 of a band saw, the saw 120 being guided over the pulley 118 and an upper guiding pulley in the usual a shaper 7 6, or other tool adapted to operate fashion, the two pulleys being supported in properly spaced relationship by a frame 130 carrying a table 132 adjustable through various angles inthe usual manner. A spring tension adjustment of the usual type ind cated at 133 serves to maintain the proper tension on the blade. Referring to Figs. 5 and 6, it will be noted that a spring 122 urges the clutch element 110 outwardly, this outward movement being limited by a pin 124 which may engage within either a shallow slot 126 or a deep slot 128 formed in the element 110. In the position illustrated in Figs. 5 and 6, the pin 124 engages the bottom of "the shallow slot. At this time the element 110 will not project sutliciently far to engage its cooperating element 114 and accordingly the shafts 82 and 116 will not be operatively connected with each other. Onthe other hand, if the element 110 is manually moved against the tension of spring 122 and turned so as to bring the pin 124 into alignment with the slot 128, the element 110 will be projected sufficiently to engage the member 114, thereby coupling the two shafts. It will be obvious that the spring 122 will permit the element 110 to yield inwardly upon the application of pressure in an axial direction. This feature is of considerable utility, as will be hereafter pointed out.

The frame 130 of the band saw assembly is pivoted at 134 to the frame about an axis transverse to the lathe bed 42. lVhen the band saw assembly is in its operative position, illustrated in full lines in the drawings, it is maintained in that condition by means of an aligning pin 136 entering aligned holes in the frame 130 and the frame of the machine and also by suitable bolts 138 pivoted to the frame at 140 and adapted to enter slots 142 formed in the frame of the band saw, this latter frame being clamped against the frame of the machine by suitable Wing nuts threaded on the bolts.

By release of the pin 136 and the bolts 138 the band saw assembly may be moved as a unit to the dotted line position illus trated in Fig. 3, wherein it lies below the level of the table 16, permitting cross-cutting of larger pieces of lumber which will be free to move over the table from which the various guides, fences, etc. have been removed. In order to limit the downward position of the band saw assembly, there is provided a rod 144 which is provided at its upper end with an elongated slot 146 embracing a pin 148 carried by a sidewise extending bracket 150 carried by the frame 130. This bracket is provided with a slide 152 which will permit inward movement of the rod 144 so that its cylindrical portion may enter a cylindrical opening 154. The slide l52'is opened so that the rod 144 may normally occupy a depending position such as is illustrated in Fig. 3. As the band saw assembly is pivoted downwardly, the rod 144 maintains floor seats within the cylindrical opening 154 as the band saw assembly reaches its inoperative position. The engagement of the cylindrical portion of the rod with the cylindrical opening maintains it in fixed relationship so that it cannot accidentally pivot out ofvertical position beneath the assembly.

While there has been described and illustrated in Figs. 1, 3 and 7 a preferred arrangement of the band saw assembly so that when it is moved into inoperative position it occupies the floor area to the rear of the lathe bed 42, which is only used when an operator is using the band saw or mortising, Figs. 11 and 12 illustrate further possible arrangements of the band saw which,

however, are less desirable in that when the stud 166, the link being clamped to the frame through the medium of a wing nut 167. The

lower inoperative position of the band saw assembly may be conveniently determined by the engagement of the stud 166 with the end of the slot 164 adjacent the pivot 160.

A further modification is illustrated in Fig. 12, in which the band saw assembly 168 is pivoted intermediate its forward and rear ends on a pivot-170 which also is parallel to the mandrel 28. A link 174 equivalent to link 162 is pivoted to the assembly at 172 and a Wing nut 176 serves to similarly hold the assembly in its operative position. Inv his case, while theentire assembly does not move below the level of the pivot 170. the pivot is located asufficient distance below the horizontal plane of the saw table so that the entire assembly is moved below this plane out of position to interfere with cross-cuttin 1% will be obvious that other arrangements than those disclosed may be used to permit the movement of the saw assembly to either operative or inoperative positions.

The mortising table 44 is described in detail and claimed in my copending applica tion Ser. No. 479,466, filed of even date herewith, entitled Woodworking machine.
